Reprocessed previous Eta Carina data WITHOUT any calibration frames (darks and flats with bias removed) and got rather different results. It was perhaps the darks that caused the loss of data rather than the flats? Same deal with exposure time from previous post and taken in heavy LP. Have tweaked the stars a little. Got lots of purple in the outlying nebulosity that I found hard to manage. Much happier with this result although lots of small processing artefacts.
